Finally, someone does it!

October 16, 2012


It is nice to see the idea I had a few years ago become a reality, even if by someone else’s hand. It always seemed so obvious to me that I was finding it very strange that no one else would be trying to bring it to market. Let’s see if Middle Tennessee State University […]

Another semester finished. Balance time and my first paper.

August 12, 2009


We finally wrapped up our group works. Yes, we dragged our feet like sloths on this one (school ended almost two months ago). Or rather, we definitely bit off more than our part-time researcher lives allow us to chew. Anyway, if you’d like to read the more or less full account of our work in […]

Rethinking the project

January 23, 2009


After 1 year and 2 months, I have very little to show for results. There is this software framework that produces sketchy models of wheel-motors which have no guarantee of real-world performance. And a web site full of interesting bits of information, a few intelligent discussions, and a handful of very nice and techie web […]

The braking problem – energy analysis

September 26, 2008


I’ve been just talking about regenerative braking for too long. It’s time to define the requirements. When trying to dimension ultracapacitors or batteries for regen braking, we have to take into account the energy and power of the braking in it’s worst case: from top speed down to zero, and in the shortest time possible. […]

The motor, in ASCII art

July 6, 2008


A fellow tinkerer has contacted me showing his own project of in-wheel motor. His design is of Axial Flux with double rotor, and he shows me a series of details and shares a few enhancements over my original axial flux single rotor design. I found this event quite gratifying; it’s the kind of confirmation I […]

Candidate selection process for motor prototype

June 23, 2008


In the past, I tried to create as many different motor simulation models as I could, in order to explore and learn about the possibilities. Halbach arrays or not, ironless or ferrous cores, one or two magnetic rotors, radial flux or axial flux, etc. Lately I’ve been making practical decisions and tweaking my simulation scripts […]

To startup, or not to startup…

June 16, 2008


I’ve been quite distracted over the past 2 months, because after asking for an enthusiast’s help on building the motor, I was introduced to a couple of business men and the whole idea got blown out of proportion… I started thinking about a conversion business, or a conversion kit franchise, and a few other modes […]
